Fellow Inspectors,
I need help with ID’ing this plastic pipe. It has no markings on it. Looks like PB, but there are no metal crimps, just the compression fitting you see. I could not trace it after it went into the ceiling. There were no other visible joints. All other piping was copper or galvanized.

It’s PB. But if you do not see crimp connectors, you’re all set.
PB manufacturers have addressed joint problems with a new type of manifold design, which eliminates the use of T-joints and other traditional fittings used with copper and C-PVC pipes. Also known as the "manablock" system, the new design runs flexible 3/8 inch PB pipes from one common source to each fixture.
Where's the meter? Are yours out at the street also?

Thanks,
The meter is out in the street. This house is 130 years old. No manifold installed. This is just one dedicated line tapped to the main supply line, but I have no idea what it serves.

Bruce,
By "all set", I think that David is confiriming PB piping. I have seen plenty of PB, but not with this typs of connection.
I always recommend any type of PB supply lines for further evaluation by a licensed plumbing contractor.

i am of the unerstanding that PB in an of itself is problematic. no mater what type of connection it uses, PB is PB. the compound is the same in any case. provided that it is PB of course.
